1st Nine Weeks Standard Review

Front

What type of cell transport is endocytosis?

Back

Endocytosis is a type of active transport where cells engulf substances from the outside environment, bringing them into the cell.

Front

What is a key characteristic of living organisms?

Back

The ability to adapt to changes in their environment.

Front

What type of cellular transport does not require energy?

Back

Passive Transport.

Front

What is osmosis?

Back

Osmosis is a type of passive transport that specifically moves water across a semipermeable membrane.

Front

What happens to a cell in a hypotonic solution?

Back

The cell gets bigger and swells due to the influx of water.

Front

Define passive transport.

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically along a concentration gradient.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy (ATP) to do so.

Front

What is the role of the sodium-potassium pump?

Back

The sodium-potassium pump is an active transport mechanism that moves sodium ions out of the cell and potassium ions into the cell, crucial for maintaining cellular function.

Front

What is the difference between endocytosis and exocytosis?

Back

Endocytosis is the process of taking substances into the cell, while exocytosis is the process of expelling substances from the cell.

Front

What is a semipermeable membrane?

Back

A semipermeable membrane is a barrier that allows certain substances to pass through while blocking others, crucial for processes like osmosis.
